People who learn by blind trial and error do it because they see fast results. They have to pay for those results with their body, but they do see results (even if their style looks insanely ugly).
However, if they applied a little smarts to how they approached their snowboarding and learnt how to do things correctly, they’d actually progress faster in the end because they’d be learning the right basic movements that they can apply to hundreds of tricks later.
Blind trial and error learning is basically swapping long term results for a short boost of progression that doesn’t last. People who learn by blind trial and error think they’re getting fast results, but really they’re shooting themselves in the foot in the long run.
